Problem copying audio CDs with PX-716A & Nero 7

Hi. I am having some problems copying audio CDs using Nero 7. This is the first time Ive been experiencing this. I have 3 optical drives (1) Lite-On SOHC-5232K, (2) Plextor PX-716A, (3) Plextor PX-716A. All drives are on a seperate IDE channel and configured as Master, DMA on. I am using a PCI IDE controller. When I try to do a quick copy using Nero Express and burning @ 48x, I repeatedly get buffer underruns and burn fails. I do have other burning apps, Alcohol 120%, AnyDVD, CloneDVD, DVD Region+CSS Free, DVD Shrink, Plextools Pro XL, and ImgBrn. All of these are up to date. But Im just wondering why Im having this problem with Nero after it has not been giving me problems until now. I tried changing settings in PlexTools. But after having no luck, changed back to defaults. As I mentioned I have been able to burn on the fly @ 48x since the beginning w/o any problem. PowerRec has always been enabled. By the way the audio CD is being read on the Plextor and is being written on the other Plextor. I have been using 80-wire round cables all along and am clueless about this is happening now. I have wasted close to 25 discs because of this. I hope someone could help me out with this. It would be greatly appreciated. Here is the error log:

connecting a optical drive on a a PCI IDE controller would normally cause compatiablity issue with burning software and even causing some features of the drive not working properly; try connect your drive to MB standard IDE port see whether it solve the problem.

Exactly … better to slave one optical disc drive than to have it connected to a PCI IDE controller card …

Hi
Im getting the same report in the log yet the cd burns/plays/scans great…I have 2 drives set on CS should i master and slave them u think? Would that get rid of that error in the report?
Thanks
John
Forgot to add…mine says burnt succesfully tho’

Hi. This problem only occurs with Nero Express 7. With Alcohol, ImgBrn, Plextools, and other apps burning is trouble-free. Im able to burn on the fly at max speed. Also this never occured with Nero 6. I am noticing this only after upgrading to Nero 7. I am using Verbatim 52x CD-Rs. Does this still mean the IDE controller is causing this? I have a Koutech IOFLEX-PIR133. It uses a Silicon Image 0680 chip. The only firmware I have for it is from the Koutech website and both the driver and firmware are from 2001. I wonder if there is a more recent and compatible driver/firmware from silicon image that could increase performance. Also I noticed in my error log, that DMA is not enabled for the driver on the Koutech controller. I don’t know of any way to enable it in the card’s bios. There’s a setting in Nero where I can let it decide the burning speed. With this, audio CDs burn fine but at 16-25x speed. I can’t figure out why I suddening cannot burn at 48x. Also this buffer underrun also occurs with the Lite-On drive that’s connected to onboard IDE. Please reply if you have any suggestions.

What are PCI IDE controllers for if not to connect to IDE drives?!?!?

If your PCI IDE controller says you can use it with CD drives then it should work with CD drives with any software. If it doesn’t you should complain to the manufacturer of the PCI card (and/or check for known problems with this card in your motherboard).

Surely it doesnt really make sense to be running both of these at the same time.
